What: /sys/bus/iio/devices/deviceX
KernelVersion: 2.6.35
Contact: linux-iio@vger.kernel.org
Description:
Hardware chip or device accessed by on communication port.
Corresponds to a grouping of sensor channels. X is the IIO
index of the device.
What: /sys/bus/iio/devices/triggerX
KernelVersion: 2.6.35
Contact: linux-iio@vger.kernel.org
Description:
An event driven driver of data capture to an in kernel buffer.
May be provided by a device driver that also has an IIO device
based on hardware generated events (e.g. data ready) or
provided by a separate driver for other hardware (e.g.
periodic timer, GPIO or high resolution timer).
Contains trigger type specific elements. These do not
generalize well and hence are not documented in this file.
X is the IIO index of the trigger.
What: /sys/bus/iio/devices/deviceX:buffer
KernelVersion: 2.6.35
Contact: linux-iio@vger.kernel.org

What: /sys/bus/iio/devices/deviceX/sampling_frequency
KernelVersion: 2.6.35
Contact: linux-iio@vger.kernel.org
Description:
Some devices have internal clocks. This parameter sets the
resulting sampling frequency. In many devices this
parameter has an effect on input filters etc rather than
simply controlling when the input is sampled. As this
effects datardy triggers, hardware buffers and the sysfs
direct access interfaces, it may be found in any of the
relevant directories. If it effects all of the above
then it is to be found in the base device directory as here.

Contact: linux-iio@vger.kernel.org
Description:
Raw (unscaled) differential voltage measurement equivalent to
channel Y - channel Z where these channel numbers apply to the

Description:
If known for a device, offset to be added to <type>[Y]_raw prior
to scaling by <type>[Y]_scale in order to obtain value in the
<type> units as specified in <type>[y]_raw documentation.
Not present if the offset is always 0 or unknown. If Y is not
present, then the offset applies to all in channels of <type>.
May be writable if a variable offset can be applied on the
device. Note that this is different to calibbias which
is for devices (or drivers) that apply offsets to compensate
for variation between different instances of the part, typically
adjusted by using some hardware supported calibration procedure.

Description:
Event generated when channel passes a threshold in the specified
(_rising|_falling) direction. If the direction is not specified,
then either the device will report an event which ever direction
a single threshold value is called in (e.g.
<type>[Z][_name]_<raw|input>_thresh_value) or
<type>[Z][_name]_<raw|input>_thresh_rising_value and
<type>[Z][_name]_<raw|input>_thresh_falling_value may take
different values, but the device can only enable both thresholds
or neither.
Note the driver will assume the last p events requested are
to be enabled where p is however many it supports (which may
vary depending on the exact set requested. So if you want to be
sure you have set what you think you have, check the contents of
these attributes after everything is configured. Drivers may
have to buffer any parameters so that they are consistent when
a given event type is enabled a future point (and not those for
whatever event was previously enabled).

Description:
Description of the scan element data storage within the buffer
and hence the form in which it is read from user-space.
Form is [s|u]bits/storagebits[>>shift]. s or u specifies if
signed (2's complement) or unsigned. bits is the number of bits
of data and storagebits is the space (after padding) that it
occupies in the buffer. shift if specified, is the shift that
needs to be applied prior to masking out unused bits. Some
devices put their data in the middle of the transferred elements
with additional information on both sides. Note that some
devices will have additional information in the unused bits
so to get a clean value, the bits value must be used to mask
the buffer output value appropriately. The storagebits value
also specifies the data alignment. So s48/64>>2 will be a
signed 48 bit integer stored in a 64 bit location aligned to
a a64 bit boundary. To obtain the clean value, shift right 2
and apply a mask to zero the top 16 bits of the result.
For other storage combinations this attribute will be extended
appropriately.
